To all whom, it 71u17/ cm1/cern:

Be it known that I, ARTHUR J. BAZELEY, of Cleveland, Cuyahoga county, Ohio, have invented a new and useful Uncoupling Device, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a front elevation of the device; Fig. 2 is a bottom plan view; Fig.13- is a ser tional elevation; Fig. 4 is a similar view illustrating a modified form of the device by whichthe fulcrum of the uncoupling lever is attached to the coupler, and Fig. 5 is a detail view of the crank.

The purpose of my invention is to provide means or the uncoupling of bottom-opening automatic couplers, and it provides a means which is simple in itsfconsltruction, and is very strong and durable, meeting well the diiiicult conditions to which such devices are ex osed when in use.

the drawings, 2 represents the couplerhead and 3 the coupler-shank of a bottomopening coupler.

4 is an elbow lever the rear arm of which -is ivoted at 4 preferably to a lug on the couper-shank, and the front arm 4 extends upwardly into an opening at the bottom of the coupler-head in which it is adapted to. engage part of the coupler-locking mechanism and to move it vertically. The elbow lever is actuated by means of a crank which may extend from' side to side of the car, and is provided with operating handles at the ends. This crank is made in sections. The middle section or crank portion proper 5 is a U- shaped piece preferably a casting having trunnions 6 which are ournaled in brackets 7 dependin from the end sill 8 of the car. This cran extends beneath the rear arm of the elbow lever 4 and when the crank is turned on its trunnion G it will engage and raise the elbow lever and actuate the lock, but as there is no positive .connection between the elbow lever and the crank, the crank does not interfere with the lateral motion of the coupler which occurs wheninuse,

and is therefore well adapted to be applied to couplers which form a part of radial draft 5c gear. The crank-shafts by which the crank 5 is operated, consist of rods 9, Q which are fulcrumed in brackets 10 near the sides of the car and at their inner ends have hooked portions 11 which fit within sockets 12 at the ends of the crank. This enables the crank itself to be made of a casting and the shafts 9 to be of wrought metal, and also enables the cranks to be made of standard size, so as to operate uniformly when in use. Only one of the shafts 9 may be used, if it is desired to operate the device from one side only of the car.

In Fig. 4 I show a modified means of applying the lug by which the lever 4 is pivoted to the shank of the coupler. Here the lug is made of a separate piece 13 which is riveted by rivets 14 to the shank of the coupler, these rivets 14 being the same rivets by which the yoke 15 of the coupler is attached.

Within the scope of my invention as defined in the claims, the parts may be modified, since what I claim is:

1. Un'coupling mechanism for car couplers comprising, in combination with a coupler having a head and shank, an elbow lever pivotally connected to the coupler-shank and \having an arm which extends upwardly to operate the coupler lock.

2. Uncoupl/ing mechanism for car couplers, 8

comprising, in combination with a coupler having a head and shank, an elbow-lever pivotally connected -to the coupler-shank and having an arm which extends upwardly and enters a hole in the bottom of the couplerhead, and an operating crank by which the elbow-lever is operated.

3. An operating crank for actuating a coupler lock, comprising a crank-shaped piece of general U-shape, with trunnions journaled in fixed bearings and having a socket for the reception of an actuating rod.

4. An operating crank for actuating a coupler-lock, comprising a crank piece. of general U-shape having its middle portion 5 extending in a direction transverse to the length of the ce1' and adapted to have a floating connection with a. lock-operating device, said piece being journaled in suitable bear- Which are common to the lug and to the 1o coupler-yoke.

In testimony whereof, I have hereunto set ings, and having mens for attachment of a my hand.
